Adam Trickett gives a short talk introducing the perl scripting / programming language. This talk does not require any previous knowledge of perl, and focuses on the community resources available rather than the language itself. See http://www.hantslug.org.uk/cgi-bin/wiki.pl?TechTalks for more details and copies of the presentation that accompanied the talk. This talk was given at the Hampshire Linux User Group (HantsLUG) meeting on 3rd June 2006 at Southampton University.
There is an OGG Theora / Vorbis version available. The archive.org site doesn't seem to recognise Theora files at the moment. Get it here:
